PLATE-TURNER FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 591,712, dated October12, 1897.

Application filed September 1, 1896. Serial No. 604,554. (No model.)

T0 all whom t may concern:

Beit known that I, JOHN S. VORTH, a citizen of the United States, and aresident of Coatesv-ille, Pennsylvania, have invented certainImprovements in Plate-Turners for Rolling-Mills, of which the followingis a specilication.

The object of my invention is to construct an apparatus by which rolledplates can be turned and inspected after they leave the rolls, andpreferably while in transit on the tables, and can also be transferredfrom one table to another.

In the accompanying drawings, Figure l is a plan View of my improvedplate-turning apparatus, and Fig. 2 is an end View, partly in section.

A are the rollers of the table extending from the rolling-mill, and Aare rolls of a continuation of the (able. My apparatus is mountedbetween these two sets of rolls and so arranged that the plate can beturned over from the rollers A onto the rollers A', so that both sidesof the plate can be inspected or the plate can be shifted from one setof rolls to the other without turning, as fully described hereinafter.

B B are two platforms, in the present instance made up of a series ofarms b, mounted on rock-shafts B2, adapted to bearings C. Theserock-shafts are arranged parallel to one another and are adjacent toVeach other, so that when the platforms are turned up, the rock-shaftsacting as a pivot, the two platforms will assume the position shown bydotted lines in Fig. 2, so that a plate carried by one can be readilytransferred to the other when the platforms are in the verticalposition. In operating the platforms I so elevate the one to receive theplate that it will be a little off the vertical line, so that when theplate is carried by the other table it will fall onto thereceiving-platform without the aid of the operator, and when theplatforms assume the position shown by full lines in Fig. 2 the platewill be on the platform B' and inverted, so that the under side of theplate can be examined as well as the top side.

F F are two cylinders trunnioned at fin bearings f. In the cylinders arethe plungers F', connected to brackets b2, projecting from the underside of the platforms. These cylinders are provided with suitable valvemechanism and fluid, (either steam, compressed air, or gas,) which underpressure will turn the platforms on their pivots.

I preferably counterbalance the table by weighted arms B3. (Shownclearly in Figs. l and 2.)

When it is wished to use the apparatus only for turning plates, plainarms may be used, but where it is wished to transfer the plates from oneplatform tothe other or move the plate laterally on either platformwithout turning then I provide each arm with atrain of rollers D, eachroller having gear-teeth, and in between the rolls are intermediatepinions (l. The arms of the platform may be set wider apart and therollers D lengthened to any desired limit, so that one set of rollersmay form a platform when preferred. The trains of gears are driven froma central shaft DI', provided with pinions d,which mesh with the firstwheels of the train on each arm. The shaft D' is geared to adriving-shaft D2 through the medium of clutches h h and gears Q @.92-the shaft D', while the bevel-gears g g2 are loose on the shaft. By thisconstruction the shaft can be driven in either direction, so that aplate on one platform can be shifted without turning onto the otherplatform.

The platforms when in the normal position, as shown in Fig. 2, areslightly below the rollers of the table, so that a plate can be rolledin position over the arms of the platform, and s when in position theplatform can be raised, as described above, to turn the plate, or whenit is wished to shift the plate from one platform to the other eachplatform is slightly elevated, so that the plate will be carried by therollers of the arms and not by the rollers of the table. The gear-trainis then set in motion and the plate is shifted from one platform to theother, or a single platform with the driven rollers may be used inconnection with a single-roller table for transferring plates laterallyfrom the table to any desired place.

t' are center bearings which support the plate on edge when it is beingshifted from one platform to the other. These bearings in the presentinstance form part of the main bearings for the rock-shafts, althoughthey The clutches h 7L are fast onV IOO may, in some instances, beformed on independendent standards without departing from my invention,and may be made concave in shape, to better steady the lower edge of theplate, instead of iiat, as shown.

I claim as my inventionl. In an apparatus for turning or transferringplates, the combination of a platform pivoted at one side, With meansfor elevating the platform on the pivots, and one or more rows of drivenrollers on said platform, substantially as described.

2. The combination in apparatus for turning plates, of the twoplatforms, a pivot at one side of each platform, and means for turningthe platforms on their pivots so as to bring them up face to face, witha space between them when in a vertical position and for turning theplatform carrying the plate past the center, whereby a plate carried byone platform can be' transferred to the-other platform, substantially asset forth.

3. The combination of the two platforms, pivots therefor, said pivotsbeing arranged at the adjacent edges, independent mechanism for turningthe platforms, a center bearing on which the plate rests, when turnedfrom one platform to the other, substantially as described.

4. The combination in apparatus forturning plates, of the two platforms,a pivot at one side of each platform, the platforms being so arrangedthat when turned to a vertical position they will be face to face with aspace between them, and independent means for raising and lowering eachplatform, so that the one carrying the plate can be turned past thecenter to transfer the plate to the other platform, substantially asdescribed.

5. The combination of the delivery-table of a rolling-mill, rollersthereon, a platform consisting of a rock-shaft and a series of arms centto the aforementioned platform, and

consisting of a rock-shaft and arms, rollers between the arms formingcontinuation of the delivery-table of the rolls, and means for operatingthe said platform, so that a plate can be turned from one portion of thedelivery-table to the other, substantially as described.

6. The combination of the pivoted platform, means for turning the sameon its pivots, a train of rollers on the platform, a second platformadjacent to the aforementioned platform, pivots therefor, and means forturning it on the pivot, a train of rollers on the platform, and meansfor operating the trains of both platforms, so that a plate can beshifted from one platform to the other, without turning, substantiallyas described.

7. The combination in an apparatus for turning or shifting plates, thesame consisting of two platforms pivoted adjacent to each other, eachplatform made up of a series of arms mounted on a rock-shaft, rollers oneach arm, geared entrain, a central shaft, gears on said shaft meshingwith the trains on the several arms, and means for turning the platformson their pivots, so that a plate can be either shifted fromone platformto the other by setting the rollers in motion, or turned and shifted byturning the platforms on their pivots, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN S. WORTH.
